Adam Lucek distinguishes regression checks from benchmarks designed to measure and improve a specific agent capability. He breaks a task into harness, state, verifier and configuration, then walks through a legal-document benchmark to show how instructions, workspace tools, source documents and explicit pass/fail criteria fit together. The example illustrates evaluation design rather than offering legal advice.
Adam Lucek emphasizes the difficult work of defining a capability, curating representative inputs and labeling desired outcomes with domain experts. He recommends environments that reproduce production conditions and warns that agents noticing incomplete mocks can undermine an experiment. Once those foundations are reliable, teams can compare changes to models, prompts and harnesses or use verifier scores as reinforcement-learning rewards. Promotional appeals are omitted, and industry examples are presented as his explanation rather than independently audited performance findings.
